Well.... it is tough to say.

New car = less mechanical problems
Old car = more potential for mechanical problems

Have you ever had the fuel pump/ filter changed before?

I have always been a person who does regular/ preventative maintenance on all my cars. Do you do this?

Could it be related to the shop..... maybe.

We need more info.

Is the shop a reliable shop? Are they experienced in european cars?

I wish you the best
